INTERNATIONAL PROGRAMME ON CHEMICAL SAFETY WORLD HEALTH ORGANIZATION TOXICOLOGICAL EVALUATION OF CERTAIN FOOD ADDITIVES WHO FOOD ADDITIVES SERIES 16 Geneva, 23 March - 1 April 1981 The International Programme on Chemical Safety (IPCS), established in 1980, is a joint venture of the United Nations Environment Programme (UNEP), the International Labour Organisation (ILO), and the World Health Organization (WHO). The overall objectives of the IPCS are to establish the scientific basis for assessment of the risk to human health and the environment from exposure to chemicals, through international peer-review processes, as a prerequisite for the assistance in strengthening national capacities for the sound management of chemicals. The Inter-Organization Programme for the Sound Management of Chemicals (IOMC) was established in 1995 by UNEP, ILO, the Food and Agriculture Organization of the United Nations, WHO, the United Nations Industrial Development Organization and the Organisation for Economic Co-operation and Development (Participating Organizations), following recommendations made by the 1992 UN Conference on Environment and Development to strengthen cooperation and increase coordination of the policies and activities pursued by the Participating Organizations, jointly or separately, to achieve the sound management of chemicals in relation to human health and the environment.

Hydrogen cyanide and its salts should not be used as such as food additives. 6. Group ADI for other glutamate, calculated and expressed as glutamic acid. 7. The statement "ADI not specified" means that, on the basis of the available data (chemical, biochemical, toxicological, and other), the total daily intake of the substance, arising from its use at the levels necessary to achieve the desired effect and from its acceptable background in food, does not, in the opinion of the Committee, represent a hazard to health. For this reason, and for the reasons stated in the individual evaluations, the establishment of an acceptable daily intake (ADI) is not deemed necessary. 8. Group ADI for pectins and amidated pectins, singly or in combination. 9. This solvent should not be used in food processing. 10. Residues of toluene occurring in foods when this solvent is used in accordance with good manufacturing practice would not pose any toxicological problems. 11. Group ADI for propylene glycol esters of fatty acids calculated and expressed as propylene glycol. 12. Group ADI. The Committee concluded that the ADI for ascorbic acid and its potassium and sodium salts should be changed from 0-15 mg/kg of body weight to "not specified", and that the calcium salt should be included in this ADI. 13. The specifications were revised to include a limit for 5-hydroxymethylfurfural of 0.05%. 14. The ADI is for polydextrose A and polydextrose N, singly or in combination. 15.
